1.3 Qualified staff
In the context of this operating manual and the information relating to
the product itself, qualified staff refers to electronics specialists who are
familiar with the installation, assembly, start-up and operation of the
drive control and the dangers involved, and whose specialist training and
knowledge of relevant standards and regulations provide them with the
necessary abilities.
1.4 CE marking
With the CE marking, we, as the manufacturer of the device, confirm that
the basic requirements of the following guidelines are met:
•Directive on Electromagnetic Compatibility (Directive
2004/108/EC of the Council)
You can download the Declaration of
Conformity at www.epa.de.
1.5 Safety instructions
The following warnings, precautionary measures and comments are
provided for your safety and serve to prevent damage to the drive control
and the components connected to it. This chapter contains warnings and
information that are generally applicable when handling drive controls.
They are split into general information, transport & storage and
dismantling & disposal.
Specific warnings and comments that apply to specific activities can be
found at the start of the appropriate chapters and are repeated or added
to at various critical points in these chapters.
Please read this information carefully as it is provided for your personal
safety and will also prolong the life of the drive control and connected
devices.

1.5.1 General information
DANGER!
RISK OF DEATH DUE TO ROTATING PARTS!
The motor can rotate during the programming. Depending on the
equipment, this can cause a dangerous situation for persons and the
equipment.
Make sure that no one is located in hazardous zones and that the motor is
disconnected.
DANGER!
RISK OF DEATH DUE TO ELECTRIC SHOCK!
Hazardous currents are present on the motor and drive control. These can
lead to injury or death.
When working on the device, de-energize the device and secure it from
being switched on again.
NOTE
This operating manual must be kept near the device and available to all
users.
1.5.2 Disassembly & disposal
Components with electronic parts may not be disposed
of along with normal household waste. They have to be
collected separately with waste electrical and electronic
equipment in accordance with applicable legislation.

1.6 Proper use
The application andperformance parameters of the @DRIVE®drive
control from EPA GmbH are displayed and programmed with the @PAD®.
This device may only be used for the @DRIVE®drive control.
This device may only beused under the allowed environmental
conditions. Incorrect use may cause damage to the device. The @PAD®
may only beused for its intended purpose. Any usethat differs from or
goes beyond the stated intended purpose is considered non-intended
use. The manufacturer accepts no liability for anydamage resulting from
such non-intended use. Modifications to the @PAD®areprohibited.
Any instance of misuse ofthe @PAD®will result in the terminationof
the guarantee, warranty and general liability ofthe manufacturer.
The @PAD®may not be operated in areas where there is a danger
of explosion.
Repairs may only be performed by authorised repair bodies. Independent
and unauthorised intervention may result in death, injury orproperty
damage. The warranty provided by EPA will be invalidated in such cases.
1.7 Responsibility
As a basic principle, electronic devices are not fail-safe. The operator
and/or the contractor setting up the machine or system is responsible for
ensuring that the drive switches to a safe state if the device fails.
The “Electrical equipment of machines” section in DIN EN 60204-1; VDE
0113-1:2007-06, “Safety of machinery” describes the safety requirements
for electrical control units. These are provided for the safety of people
and machines and must be observed in order to retain the functional
capability of the machine or system.
An emergency stop feature does not have to result in the power supply to
the drive being switched off. To avoid dangerous situations, it may be
useful for individual drives to remain operational or for specific safety
procedures to be initiated. The effectiveness of emergency stop measures
is evaluated by means of a risk assessment for the machine or system and
its electrical equipment, and is determined by selecting a circuit category
according to DIN EN 13849 “Safety of machinery – Safety-related parts of
control systems”.

3.4 Motor detection
DANGER!
RISK OF DEATH DUE TO ROTATING PARTS!
The motor can rotate during the programming. Depending on the
equipment, this can cause a dangerous situation for persons and the
equipment.
Make sure that no one is located in hazardous zones and that the motor is
disconnected.
DANGER!
RISK OF DEATH DUE TO ELECTRIC SHOCK!
When working on the device, de-energize the device and secure it from
being switched on again.
Procedures:
1 De-energize drive control.
2 Unscrew the four screws from the drive control housing cover and
remove the cover.
3 For the hardware enable, connect the 24-volt DC hardware to the
@DRIVE
®
,connect the application board to the "En.HW"terminal.
This voltage can be supplied externally or from
the "24V out" terminal. For these, refer to the
@DRIVE
®
operating manual.
4 Screw the cover onto the drive control housing.
5Connect the communication cable tothe @PAD
®
and the @DRIVE
®
drive control.
6 Switch on the power supply for the drive control.
On the @PAD
®
display, the start screen appears and then
the menu.

The motor type is configured for asynchronous motors
(value 1) by default.
For synchronous motors, the value must be changed to

parameter > Motor type)
7 Determine the following six motor data from the type plate (see
example)
Fig. 6: Motor type plate (example)
No. Menu item inthe @PAD®According to the example on the
template
1. Motor current 26.5 A

9 Enter and save the six types of motor data from the type plate with
the @PAD
®
under the corresponding menu items. (The values for
"stator resistance" and "leakage induct." are determined during motor
detection.)
*) These values are automatically determined and entered during motor detection.
Fig. 7: View of menu structure for motor data
Always observe the following during motor detection!
Asynchronous motor: The shaft must not rotate during
motor detection.
Synchronous motor: The shaft must be unencumbered
since it occasionally rotates during motor detection.
10 Call up the 30.Automatic Motor detection menu and start motor
detection.

Red and green LEDs light up during motor detection
Motor detection lasts 30 -60 seconds. Motor
detection is completed when the @DRIVE®is
restarted and the greenLED on@DRIVE®lights up
continuously.
If the @PAD®is unpluggedfrom the M12 interface
during the activecontrolling process,the @DRIVE®
stops with error21 (Bus Time-Out) andthe red LED
lights up continuously.
The motor detection is completed.

3.5 Specifying nominal value for the rotation speed
With the @PAD
®
,a nominal value (in %) can be specified for the
rotation speed. This nominal value is specified as a percentage
of the nominal motor rotation speed.
The ACTUAL rotation speed can be read on the display. With the "START"
and "STOP" button, the motor is switched on and off.
If the minimum frequency is > 0, the motor continues to
rotate at the minimum frequency after switching off the
nominal value. (02Parameter group (Expert
mode)>Basic parameter>Low speed)
Procedures
1 As the nominal value source, set "3: MMI/PC" (02.Parameter groups >
Basic parameter > Reference channel)
2 As the software enable signal, set "9: "Autostart" and save
(02.Parameter groups > Basic parameter > Enable software )
3 Under the menu item "40.Control", set a nominal value in %. Using the
"UP", "DOWN", "LEFT" or "RIGHT" arrows, set the desired percentage.
A negative nominal value causes a change in direction
of rotation
.
4 Press the "START" button and start the motor.
The motor rotates. The actual rotation speed is displayed in the
@PAD
®
.
With the @PAD
®
,the motor can beswitched on andoff
and anominal rotation speed can bespecified.
